Definition for Pulmonary edema
From Biology Forums Dictionary
Pulmonary edema is fluid accumulation in the air spaces and parenchyma of the lungs. It leads to impaired gas exchange and may cause respiratory failure. It is due to either failure of the left ventricle of the heart to adequately remove blood from the pulmonary circulation, or an injury to the lung parenchyma or vasculature of the lung ("noncardiogenic pulmonary edema").
